Anyone dumb enough to be "tricked into performing" really has no one to blame but himself/herself. And in the case of teens who get "tricked" into doing it, it's a combination of an imbecile minor and a lazy parent.

That's really a sidebar, and Schneier's quote at the end sums it up nicely.

The gist of the article is some miscreant can create a video, post it to a major service and claim it's you, while using your legitimate e-mail address. In this case Vimeo fixed the hole that allowed it but it won't be the last time this happens. How many unsophisticated users will be so shocked or upset that they'll do whatever the poster wants?
